Bike Master Lithium Ion Battery DLFP-51913

The Bike Master Lithium Ion line of batteries feature the most advanced high-power Lithium Iron Phosphate technology from BikeMaster. They offer ultra high cranking amps in a lightweight and small package that is ⅓ the weight and size of your traditional lead acid. They also feature a built-in charge and equalizing protection board to prevent battery overcharge.

The recharge rate is lightning fast and these batteries can reach full capacity within minutes versus the old style batteries that if quickly charged would merely gain a small percentage of their full capacity. The other advantage of the Bikemaster Lithium Ion batteries is the ease of maintenance. The batteries come sealed and ready for use and requires no additional fluids. This eliminates battery acids leaking out and possibly damaging your paint finish.


  • Can be charged using a conventional 12V lead-acid battery charger (without pulse charging function) or a specially designed LiFePo4 battery charger
  • Cylindrical cell with energy storage welding technology for higher output
  • Remarkably low self-discharge for extended storage periods up to one year
  • Suitable for low temperature environments
  • More than twice the service life of conventional lead acid batteries
  • Superior vibration resistant construction allows multi-directional installation without damage
  • No corrosive liquids and toxic heavy metals make the BikeMaster Li-On batteries environmentally friendly
  • Dimensions: 185mm L x 80mm W x 170mm H
  • Weight: 4.4lbs
  • 375 CCA (Cold Cranking Amps)
  • Battery Terminal Location:

Note: RevZilla recommends charging and testing all batteries prior to using.

Excellent fit and replacement
This battery is amazing! I bought this for my 2002 BMW R1150GS. It is a direct replacement for the stock battery. It fits snug with no need to add foam around it to fill up battery compartment. It looks as if it could have came in the bike from factory. It has the exact same post setup, it is a third of the weight of stock battery and has over twice the rated cranking power. Haven't had it long so I can't say about its long term longevity but so far ---VERY HAPPY!

Failed after 2 months
Battery didn't seem to have any more starting power than a conventional lead acid battery and that was at 70 deg F. I'm told that performance goes way down with temperature. After 2 weeks of not riding the battery was dead and would not hold a charge. Testing with another battery found there was no drain on the battery with the key off so I don't know why the battery was dead. From what I've read, once they get dead, they stay dead unless you do some radical shock therapy which would void the warranty. Replaced it with an AGM battery from Revzilla since all they offered was store credit, but at least it was hassle free. I like these guys.
